Abstract

The invention discloses a fuel consumption testing device for excavators. The fuel consumption testing device comprises a first flow meter, a second flow meter and a controller; the first flow meter is used for acquiring a first flow of a fuel inlet end of a fuel tank of an excavator; the second flow meter is used for acquiring a second flow of a fuel return end of the fuel tank of the excavator; the controller is connected with the first flow meter and the second flow meter; and the controller comprises a first processing module and is used for determining instantaneous fuel consumption according to a difference value of the first flow and the second flow and creating a mapping relation between the instantaneous fuel consumption and time. The fuel consumption testing device for the excavators has the advantages that a data foundation is provided for various follow-up fuel consumption computation and analysis, and data acquisition and fuel consumption analysis procedures can be automated advantageously.

Description

technical field [0001] The invention relates to a fuel consumption test technology, in particular to an excavator fuel consumption test device. Background technique [0002] Fuel consumption has always been an important indicator to measure the performance of excavators. There are many traditional methods for excavator fuel consumption test, one of which is to indicate the change of oil level before and after the test through the liquid level gauge, and then obtain the fuel consumption after the completion of the test through calculation; the other is to use the compensation method, before starting the test Fill up the fuel tank, and fill up the fuel tank again after the test is completed. According to the amount of fuel compensated after the test, the fuel consumption during the test can be obtained. The above-mentioned methods have a limited test range for fuel consumption, and mainly measure the flow values ​​at two points before and after the test, so as to obtain the f...
